From this thread over on Cable Forum:
"I have fitted 5 over the last 2 days. We are being instructed by Virgin to make sure all new install get the Samsung so now is the time to order in Notts.
They are great, channel changing is quick, there is nothing between it and my Sky HD box so it looks like that old complaint is over and done with.
PQ is just the same as the SA. No Component, No RF. VCR scart always active with menus.
Overall this box is what we have been waiting for. Now just lets get more HD."
"I noticed it was much sharper straight away on HDMI. Also menu at 1080 looks great. Haven't got any complaints about the box at all."
